3 Introduction Cirrus, Altocumulus, Nimbostratus, Stratocumulus, Contrails, Billow, Mammatus, Orographic, and Pileus are all types of what? You may be scratching your head on this question; so to assist you the answer is Clouds. As you may recall from grade school not all clouds share all the same features, shapes, or sizes, but they are all considered clouds. However, if you are planning an outdoor event the specific type of clouds becomes very important and critical to your success so know your cloud types. Now look at these, SaaS, IaaS, and PaaS are all types of what? Correct Cloud Computing offerings a.k.a Cloud. As with the clouds of nature these types of cloud computing do not share all the same features, functionality, security, and cost structures, but are considered an implementation of Cloud. As with knowing the cloud types for a successful outdoor event, knowing which type of Cloud can be leveraged by a consumer is critical to transforming the way IT services are delivered. Cloud has quickly become an emerging trend that has introduced significant benefits as well as confusion in the IT industry. The term is applied freely to various implementations of IT solutions thereby making it extremely difficult to know if an IT solution, designated as a cloud computing offering, delivers on the promises of Cloud or is just a marketing pitch. Common Cloud Computing Types SaaS IaaS PaaS Description Software as a Service Infrastructure as a Service Platform as a Service Figure 1 Cloud Watcher's Cheat Sheet To this end, Companion Data (CDS) welcomes the opportunity to provide this document as a reference guide to demystify the world of Cloud. Cloud DNA Is Cloud a revolutionary technology or a transformation of traditional IT service delivery? The last acknowledged revolutionary technology was client/server. This revolution was initiated by the introduction of Intel s x86 server / workstation hardware into the IT environment that was dominated by mainframes and micro computers. Intel s entrance into this environment has forever changed the capabilities of computing. Looking at IT environments that are supporting Cloud, it is clear that the improvements in virtualization technologies played a major role in the growth of Cloud. Cloud could technically occur without virtualization, but it would be a difficult economic model to sustain. Other than the improvements noted in virtualization technologies, there is no evidence supporting the entrance of a revolutionary technology that created the Cloud. This leaves the transformation of traditional IT service delivery as the genesis of the Cloud marketplace, but why? Page 1

4 In the progression from the traditional IT service delivery model, care must be given to characteristics of the IT services being considered. Specifically, there are two basic types of IT services: Horizontal: that are normally standardized across all consumers like , SharePoint, Office Apps, human resource (HR) systems, enterprise resource planning (ERP) and other office automation systems, etc. This similarly affords the Cloud provider the opportunity to leverage a large amount of computer resources in hardware, software, and operational maintenance, thus producing an aggressive cost structure to the consumer. These services are normally the lowhanging-fruit where the consumer and Cloud providers can achieve quick successes. Vertical: that are normally different across consumers and require specific environmental customizations, such as specialized security requirements, unique to the consumer, thus making the service unable to be leveraged by the provider across their delivery portfolio. These services are specific to each consumer or a small set of consumers and have less standardization, more customization and a higher subscription usage cost. As the above discussion explains, horizontal services are highly scalable and share a highly leveraged and standardized infrastructure to provide access to a large population of unrelated users. Vertical services are less standardized and more customized with a smaller population of related users. These generalities hold constant when the Cloud is established as a Public Cloud and not as a Private Cloud. Public Cloud services are accessible by a limitless number of unrelated consumers; whereas Private Cloud consumers are normally smaller in scope and are related (i.e. employees of a corporation, the federal and state governments). It is this reduction in scope of a Private Cloud that brings features of vertical services into the horizontal services profile: Standardized to the smaller related group of consumer s requirements Customization to the smaller related group Dedicated infrastructure resources to the services of the Private Cloud Increases in the cost structure as compared to the same service provided by a Public Cloud Figure 2 illustrates how Cloud is delivered as compared to traditional IT services. This figure presents the progression of IT service delivery models from a traditional on-premise delivery model transitioning to an Internet service delivery model. Page 2

5 Figure 2 IT Service Model Evolution There are some interesting consequences, worth noting, that occur as a consumer migrates away from a traditional model. These consequences represent the promises and concessions that the Cloud brings to the marketplace. The following describes these promises and concessions from both a consumer s and provider s viewpoint. Page 3

6 Promises Cost Structure: is moved from a capital intensive structure to a usage-based subscription cost structure and incurs a reduction in his internal IT labor costs, thus improving cash flow. Flexibility / Agility: can quickly stand up new computing resources, without any capital expenditures, using the excess capacity made available from the provider as part of the subscription cost. On-Demand : incurring fees. can increase / decrease capacity as necessary without Concessions Less Functionality / Integration: concedes functionality to achieve a reduction in cost and flexibility in service delivery. Please note, there is one area that the consumer will have major difficulties in conceding functionality and that is security. In fact, this has been the major area that has restrained the growth of Public cloud computing offerings, whereas in a Private cloud computing offering, security functionality can be implemented to the consumer s requirements. Increased Standardization: concedes specific technology architecture / configuration deployments and upgrades. Less Customization: concedes to use the service as delivered without specific organizational modifications. Provider Promises Less functionality / integration: The provider normally provides less functionality than what is installed in an on-premise solution to enable support for the consumer s cost structure requirements and resource requirements. Increased standardization: Provider provides a standard resource offering for all consumers. Less Customization: Provider provides limited customization to reduce maintenance costs to the consumer. Provider Concessions Cost Structure: Provider assumes the risk of acquiring and maintaining the computing resources for the subscription-based consumers. Flexibility / Agility: consumer s request. Provider must enable the ability to quickly standup resources for the On-Demand : Provider must be able to handle increases and decreases in resource requirements. The IT services delivery model foundation portrayed in Figure 2 serves as the backdrop against which specific IT services can be applied. This is in an effort to determine if from a: View: Can a consumer gain an economic and/or competitive position by transforming from a traditional IT service delivery model? Page 4

7 Provider View: Can a provider gain economic advantage and market positioning by offering other IT service delivery models? The concept that the Cloud s DNA is first and foremost the movement to transform the traditional IT service delivery models is more than just a simple thought. To this point, Figure 3 illustrates just one of the transformations from traditional IT service delivery to a Cloud delivery. Specifically, Figure 3 demonstrates the movement of IT services from the Traditional Service Delivery model to the Software-as-a-Service model. To see the complete grid of IT Service Delivery transformations, please review Figure 6 in Appendix A.

8 When viewed in this manner, the confusion around the various technical implementations of Cloud are replaced with a view of the new IT service delivery models. These models are analyzed on factors such as how they can lower cost, add flexibility and add agility, therefore making Cloud a business choice and not a technology choice. CMS Enterprise Data Centers Through the Lens of a Cloud Imagine 22+ data centers across the United States all executing the same set of claim systems to process a portion of a larger base of subscriber s / provider s claims. Within each data center are dedicated computer resources (hardware and software), labor, power and vendor support to ensure the successful completion of the claims workload. Looking back at Figure 2 in the Cloud DNA Section, the IT service delivery model for the above scenario would be a traditional IT service delivery model for all 22+ sites. Additionally, the main IT service is vertical in nature because there is no single claim system that can be used for all worldwide companies performing claims processing; however, there can be a set of standardized claims systems for this related group of consumers. This scenario was in place prior to the establishment of the Enterprise Data Center (EDC) program that CMS began more than five years ago knowing that a transformation in the way IT was being delivered was necessary to reduce the administrative cost of processing claims while improving security. The ID/IQ for the CMS Enterprise Data Centers contract model has allowed CMS to selectively acquire IT services for claims processing in a new IT service delivery model the EDC IT service delivery model that: Provides a lower cost of IT services through the consolidation of 22+ Data Centers into two Enterprise Data Centers Provides a centralized set of claims systems accessible by a related group of consumers via a private network Creates a supporting infrastructure standardized to CMS requirement as outlined in the Technical Reference Architecture (TRA) Incorporates subscription based pricing by number of claims processed per month Provides the flexibility and agility to bring new claims workloads on-board without having to create another data center that would be necessary if using the traditional IT service delivery model Should the EDC IT service delivery model be considered as a Cloud solution? The comparison contained in Figure 4 presents a straightforward alignment of the EDC solution to the Cloud s Software-as-a-Service solution therefore, showing that the EDC is technically a Private Cloud solution. EDC IT Service Delivery Model Cost reduction through consolidation of 22+ Data Centers Centralization of the Claims Systems via a Private Network Software-as-a-Service (Private Cloud) Reduce cost through standardization and increased scale Via the Cloud (aka: Network) provides access to a standard Software service Page 6

9 EDC IT Service Delivery Model Creation of CMS standard infrastructure Cost-per-claim More flexibility in adding claims workloads Software-as-a-Service (Private Cloud) In a Private Cloud strong standardization, with limited customization to the related group of consumers Subscription based pricing Workload flexibility and agility Figure 4 IT Service Delivery Model Comparison Since the start of the EDC program, Companion Data has received several additional non-claims workloads that also align to the Cloud s IT service delivery models. For example: National Data Warehouse (NDW) Aligns to Software-as-a-Service National Level Repository (NLR) Aligns to both Software-as-a-Service and Platform-as-a-Service While the EDC program was not specifically labeled as being a Cloud program by CMS, it unquestionably has the characteristics of the Cloud movement. It is an IT service delivery model that lowers cost, adds flexibility and agility, and provides accessibility to selected consumers. EDC Program as a Cloud Offering As shown in section three the EDC program embraces the major foundational element of the Cloud movement. However, there are several other elements of Cloud that should and should not be considered for incorporation in the EDC program. As for the should not(s), recall from section two that there are horizontal and vertical services that can be offered via the Cloud. The EDC program is well positioned to handle any CMS vertical service that would be transformed from a traditional service delivery model. However, the majority of horizontal services, like collaboration applications, are better served by the larger Cloud vendors, not as the result of the EDC program s inability to offer the service, but because of the price point provided by large Cloud vendors, like Microsoft and Google, due to their scale. As for the should(s), the EDC program serves many consumers, but its related consumer group is confined to CMS. This confinement produces a highly customized, standardized, and secured IT infrastructure that conforms to CMS Technical Reference Architecture a CMS Private Cloud. Additionally, as CMS progresses toward its vision of redundant Virtual Data Centers, this will further strengthen the CMS Private Cloud as a world-class Cloud offering. Leveraging the CMS Private Cloud, the EDC program could also offer test and development Private Cloud offerings such as Infrastructure-as-a-Service and Storage-as-a-Service for CMS and its business partners consumption in the form of secured virtual guest(s), LPAR(s), and tiers of storage. As explained in this section, there are a few items that could be incorporated into the EDC program s Private Cloud offering that would initiate additional Cloud feature utilization. However, it is important to note that the core of the EDC program has already embraced and benefited from the major elements of the Cloud movement transformation of the traditional IT service delivery models. Page 7

10 Companion Data as a Cloud Vendor Achieving the designation and recognition that the EDC program is already a Cloud solution has been difficult due to the market hype on what Cloud is and is not. The same is true for Companion Data (CDS) in its recognition as a Cloud provider. The market hype seems to be focused on providing and/or using Public Cloud solutions for the horizontal services collaboration applications like and office applications. This focus does not portray the actual activity that is occurring; which is the transformation of the traditional IT service delivery model into new IT service delivery models that lowers cost, adds flexibility and agility, and provides accessibility to selected consumers. CDS has a proven track record of being able to transform itself into new IT service delivery models in a Private Cloud environment as seen in the IT service delivery transformation of the EDC program. The environment created for the EDC program incorporates all the technology and operational process knowledge necessary to provide Cloud solutions: Networking Capabilities Virtualization Capabilities z/os IBM s top 2% data centers in size and technology z/linux Top 1 percent install-based in the United States and top 15% in the World VMWare Large deployment of Windows and Linux guests Storage Multi-vendor virtualization and thin provisioning Labor 2,000+ IT Professionals Physical Environment Enterprise Class Data Center ITIL Process Adoption DOD, CMS, HIPAA, PCI Security Posture Assessing Cloud competencies from the lens of the EDC program does provide a yard stick on which to appraise CDS capabilities in the Private Cloud market space; as would evaluating CDS capabilities against industry Cloud leaders which provides a comparison of CDS capabilities in the Public Cloud market space. Therefore, using Infrastructure-as-a-Service Cloud offering as an example, features offered by industry-leading Cloud providers have been documented for comparison. Figure 5, an excerpt of the matrix, illustrates the alignment between CDS and Public Cloud industry leaders (the entire matrix can be found in Appendix B). Features CDS Vendor 1 Vendor 2 Vendor 3 Provisioning Rapid Server Deployment Load Balancer (HW/ SW) Multi-Tiered Networks Limited Shared Servers Dedicated Servers N/A Hybrid Hosting Solutions Private Network Connections TBD Figure 5 Cloud Computing Capability Matrix [Excerpt] Page 8

11 Therefore, while CDS does not currently offer Cloud solutions in the horizontal services space, its offerings in the vertical space, as seen in the EDC program and the comparison to industry Cloud providers, demonstrate CDS capabilities as a Cloud provider. Summary There is in fact a movement underway that is changing the method in which IT services are being consumed. This movement is not based on a revolutionary technology, but on a transformation from the traditional IT service delivery models to new IT service delivery models that come with: Promises Lowers cost Adds flexibility and agility Concessions, to varying degrees, in Customization Standardization Functionality The industry is calling this movement Cloud Computing or just Cloud. And while the name is catchy, it does cause confusion for consumers that are questioning themselves about their entrance into this brave new world. Therefore, demystify this world by knowing your Clouds and the business impacts / disruptions that each type of Cloud would cause to your organization. Page 9
